3 Claims.

Wringers, as at present made, ordinarily provide a pair of wringer rolls which are subjected to yielding pressure through a spring. Means are usually provided for varying the pressur of the spring.

The present invention is designed to improve the pressure adjusting means by providing devices for indicating the pressure adjustment so that the operator without trial may provide the proper adjustment for the type of clothes which are being passed through the wringer. Other features and details of the invention will appear from the specification and claims.

Preferred embodiments of the invention are illustrated in the accompanying drawings as follows:

Fig. 13 shows a bottom view of a part of the adjusting and indicating mechanism.

Fig. 14 shows a side elevation of the part shown in Fig. 13.

Fig. 15 shows a top view of the mechanism shown in Fig. 14.

In the different modifications similarly formed parts are similarly numbered. In many of the modifications the standard frame rolls and top structure are used.

In the modification shown in Fig. 1, l marks a base of the wringer, 2 side stiles, 3 a top bar arranged on the side stiles, 4 a lower roll, 5 an Divided and this application June 9,

upper roll, 6 and I shafts for the rolls 4 and 5 respectively, 8 lower bearings for the shaft 6, bearings 8 resting on brackets 9 in the stiles 2.

Movable bearings 10 are slidingly mounted in the stiles and journal the shaft 1. A spring II operates on the upper bearing and furnishes yielding pressure for the rolls, the spring being countered by the top bar.

All of the parts so far described are or may be of standard construction.

A safety release is arranged on one end of the top bar. The release device shown is similar in construction to-that disclosed in my application Ser. No. 621,921, filed July 11, 1932, Patent No. 2,216,197, dated Oct. 1, 1940, but any release device operating between the top bar and stile may be used. The release device has a trip lever l3 which carries an inwardly projecting plate I4, this plate extending through openings I5 in the top bar 3. The trip lever is yieldingly held in its set position by a spring [1. A latch I8 extends around the stile, the sides of the latch having openings I9 pivoted on the projections 20 extending from the sides of the stile. The latch has a hook 2I engaging the plate M. The latch also has a shoulder 22 adapted to engage the rear of the plate. When the trip lever I3 is forced down it tilts the plate I4, thus bringing the rear of the plate free from the shoulder 22 and inclining the plate so that the hook I l slides off the plate and releases the top. The release device is actuated by a bar 23 which engages an extension I3a on the trip plate I3. The bar 23 is pivotally mounted at its ends in the top bar.

The resetting mechanismat the opposite end of the top comprises a resetting lever 24 pivoted at 25 on the top bar and pivotally connected by a thrust link 26 on the side stile. When the lever is drawn up the end of the top bar is released and can be separated from the stile and when the lever is forced down the toggle action of the lever and link draws the top bar down into position. In the general operation of this feature, the safety release device may be operated and in resetting the end with the safety release, may be re-engaged with the resetting mechanism in open position. By forcing down the resetting device, the top bar is forced down, putting the desired pressure on the spring. The release of the top bar may be also accomplished by the action of the resetting lever which releases the reset end of the top bar and then the opposite end of the top bar may be unhooked.

A pressure setting mechanism or block 21 is rotatingly mounted on a pin 28. The pin extends tent sockets 52.

through slots 29 in a clip 30, extending upwards from the spring. Projections 3| extend from flanges 32 which are secured to the under side of the top bar. These projections are provided with slots 33 through which the pin 28 extends.

The rod 28 extends through slots 34 in the side walls of the top bar. The setting mechanism 21 is in the form of a hexagon having three radial dimensions 36-36, 3|3'| and 3838. The member 21 has a perforation 35 extending diametrically through it which receives a locking pin 35a which extends through this perforation and the perforation 2 3a in the rod.

Handles 39 are fixed on opposite ends of the rod, the front and rear faces of the top bar and. the faces of these handles having index markings 40. It can readily be seen that with the resetting mechanism released the pressure setting mechanism 21 may be rotated through the action of the rod 28 by handle 39 so as tointerpose the short dimension 3636 to give the lowest pressure; on the long dimension 38-33 to give the highest pressure, and the intermediate dimension 3'|3l to give the intermediate pressure, and the pressure setting will be indicated by the markings 40.

The modification shown in Figs. 6 to 9 has the same safety release and resetting mechanism as that shown in Fig. 1. In this modification the pressure adjusting mechanism comprises an eccentrically shaped structure 4| which is journaled on a rod 42. The rod 42 is arranged in slots 43 of posts 44 secured by a clip 45 extending around the spring. The different projections 46, 41, and 48 are adapted to be brought into contact with the spring and interpose a greater or less dimension between the contact projection and a cylindrical surface 49 on the opposite side of the member 4|. Index projections 56 are arranged on the periphery on the member 4| and these have the index numerals on their faces indicating adjustments. The projections extend through a slot 50a so that the top numerals may be readily observed at the top of the cross bar.

In order to hold the member 4| in adjusted position a click having inturned arms 5| extends through the slots 43 and into grooves having de- Th arm 5| extend inwardly from spring arms 5|a carried by a loop 53.

In the structure illustrated in Figs. 11 to 15 the wringer frame, top bar, release device and resetting device are similar to that shown in Fig. 1. The pressure setting mechanism comprises a pin 54 fixed by a clip 55 on the spring. A pressure setting member 56 is .rotatingly mounted on the pin. It is provided with varying length of pairs of opposing projections 51. By rotating the member 56, when the top bar is in released position, any pair of these projections can be interposed between the spring and the top bar so that in resetting the top bar the adjusted pressure may be achieved. The member 56 has afiange 53 which extends through slots 59 in the front and rear of the top bar 60. The member 56 is locked in its adjusted position by raised portions 58a which engage notches 66a in the top bar 60, these notches extending from the slot 59. The flange has a series of groups of notches, 1 notch, 2 notches, and 3 notches which may be brought into position in the slot 59 and by this positioning the long or short projections 51, as indicated by the notches are interposed in the spring so as to control the pressure variations. In Fig. 11 the maximum adjustment is shown and as the member 56 is turned it will take care of the other adjustments.

This application is a division of application No. 62,605 filed February 6, 1936, now issued as Patent No. 2,201,540.
